AI files stopped displaying preview in Cloud Library

[stefanf64737634]

Since one of the last updates of Illustrator there's an error when i try to add AI Artwork to the creative cloud library. 
The newly added elements wont show me previews in any Adobe Applications "library" window or in the browser view of my cloud files. All other members of the cloud library group that i have invited are shown the preview thumbnails as before with no problems.

I tried logging out and in again and re-installing illustrator already.
